OSTRO Gravel Force AXS Gravel Bike

Factor OSTRO Gravel Force AXS Gravel Bike

The Factor OSTRO Gravel Force AXS Gravel Bike is equipped with SRAM's exemplary Force AXS 2X wireless electronic drivetrain and a built-in power meter. This performance gravel bike allows you to track every watt while maintaining flawless control over loose, technical, or unpredictable terrain.

Built for off-road cyclists who prioritise efficiency, precision, and low weight, the OSTRO Gravel transforms every ride into a high-speed adventure. Factor’s focus on aero-optimised tube shapes and a lightweight carbon lay-up delivers exceptional stiffness, responsiveness, and comfort. Whether racing, training, or exploring new gravel roads, this versatile gravel bike offers the perfect combination of speed, stability, and adaptability to tackle every challenge with confidence.

Aero-Optimised for Real-World Gravel Racing

Borrowing technology from the aero-road OSTRO VAM, the OSTRO Gravel applies a ‘zoned aero’ approach: the front of the bike is optimised for airflow, while the rear focuses on lightness and ride quality. Factor’s engineers spent extensive time refining the head tube shape, reducing drag at typical gravel speeds and manipulating airflow around the frame. The result? A bike that saves minutes, not seconds, getting you to the finish line faster in real-world racing conditions.

Versatile Geometry and Tyre Clearance

With 45mm tyre clearance on both 700c and 650b wheels, the OSTRO Gravel can handle the muddiest, roughest, and most technical terrain. Its steering geometry is designed around tyre size, ensuring precise handling whether using a 32mm all-road tyre or a 43mm gravel tyre. A lower bottom bracket, short chainstays, and optimised head tube angle provide a nimble, responsive ride without sacrificing stability, even on challenging off-road courses.

UDH and Black Inc THIRTY FOUR Wheels

The OSTRO Gravel features a Universal Derailleur Hanger (UDH), supporting the latest SRAM AXS wireless groupsets while protecting your drivetrain in crashes. Complementing this, the Black Inc THIRTY FOUR carbon gravel wheels maximise aero performance while maintaining crosswind stability. Their 25mm internal width and hookless design make tubeless setup simple, while CeramicSpeed bearings ensure ultimate efficiency across all terrains.
